Sound too low

Few days ago I hooked my PC, with a build-in Realtek ALC888/1200 sound card to my Dolby D sound system using an AUX cable. After that I plugged it back to my Hi-Fi system, which I'm using as speakers(again with the AUX cable). The problem is that two-three days ago I'm experiencing problems with sound. It's too low! First I thought it was a driver issue but it wasn't(after reinstall of motherboard and sound card drivers). Secondly I thought it was a Windows related issue, so I reinstalled the OS(it was time to do it, anyways). The problem didn't go away.

SIC, Start>settings>control panel>sounds & audio devices>audio tab>sound playback>volume. Is the proper device selected? Can you adjust any of the sliders? Same for the others. Be sure your settings are correct,HTH.Ed in Texas.

"Your sound card wasn't designed to operate more than your computer system which has it's own pre-amp."that statement makes no sense whatsoever.

Sound cards do not operate your computer system. Sound cards have their own built in preamp which controls the volume and equalizer. They are meant to output to a line level input such as your setup or to a pair of speakers with it's own built it amplifier.

Snausages, perhaps my terminology was incorrect (semantics?). My understanding of a sound card is that it's designed to provide a rather weak sound signal. Certainly not strong enough to drive a bank of auxiliary speakers. That requires amplification. 'Pre amp', 'amp'??? Anyway, a separate 'in-between' critter.Ed.
